Ch 13 Neurocognitive Disorders Flashcards
Neurocognitive disorder
Temporary transient or permanent brain malfunctions triggered by changes in brain structure or biochemical processes result in impaired thinking memory or perception changes in behavior consciousness and emotional stability. Severe injury to the front regions of the brain display impulsive behavior including saying or doing things without thinking
Major neurocognitive disorder
Condition involving significant decline in independent living skills and one or more areas of cognitive functioning. Shows significant decline in both of the following: one or more areas of cognitive functioning involving attention and focus decision making and judgment language learning and memory visual perception or social understanding, and the ability to independently meet the demands of daily livingmust involve a decline from higher levels of functioning
Dementia major cognitive disorder
Decline in mental functioning and self help skills from a major neurocognitive disorder. Condition with symptoms involving deterioration in cognition and independent functioning. May forget names of significant others are past events may display difficulties with problem-solving and impulse control. Agitation due to confusion or frustration is common. typically has a gradual onset followed by continuing cognitive decline. Age is the strongest risk factor. The longer a person lives the greater the chance of developing dementia. 15% over 70. Because women live longer they are more likely to develop dementia
Mild cognitive disorder
Minus the Klein and at least one major cognitive area. Degree is more subtle than in major. Often able to participate in normal activities but may require extra time or effort for complex tax. Accommodations to maintain independence may be required such as someone to manage finances but overall independent functioning is not compromised. Maybe an intermediate stage between normal aging and major neurocognitive disorder or dementia
Delirium
Acute state of confusion involving diminished awareness disorientation and impaired attentional skills. Can be caused by exposure to toxins or medication or from alcohol and drug intoxication with drawl. Cora characteristics differ from mild in major neurocognitive disorder: disturbances in awareness and difficulty focusing maintaining or shifting attention as well as abrupt onset and fluctuating course. Develops over a period of several hours or days can be mild or severe can be BRIEFR last for several months. Cognitive difficulties include confusion regarding where they are or time of day. Wondering attention disorganized thinking and rambling irrelevant or incoherent speech may be present. May also have psychotic symptoms.symptoms can range from agitation and combativeness too drowsy unresponsive behavior.
Neurodegeneration
A progressive brain damage due to neurochemical abnormalities and the death of brain cells such as in Alzheimer’s. They show a decline in function rather than improvement in contrast to stroke or Trumatic brain injury or substance-abuse. Can be a cause of neurocognitive disorder’s. Nero degenerative disorders include Elsheimer’s disease, dementia with Lewy bodies,Parkinson’s disease, Huntington’s disease, frontotemporal lobar degeneration, Aids dementia complex
Event causes of neurocognitive disorder’s
I Seemic stroke, hemorrhagic stroke, Trumatic brain injury, substance-abuse
Medically induced coma
It deliberately and just state of deep sedation that allows the brain to reset and he’ll
Trumatic brain injury
A physical and or internal injury to the brain. Degree of impairment in corset recovery very significantly. 1.7 million people for you and care for head injury, most common in young. 2% of the population has a disability related to Trumatic brain injury. Head injury contributes to one third of injury related deaths. Diagnosis requires persistent cognitive impairment due to the injury and that the person had experienced loss of consciousness amnesia disorientation or confusing following the event or received and are logical test the document to bring dysfunction. Can be temporary or permanent mild to severe.
Talked and die syndrome
A blow to the head can cause an unrecognized injury such as read in between the snow in the brain resulting in rapid and unexpected death.
Symptoms of Trumatic brain injury
Depend on the severity of injury and area of brain injured. Also very with persons age. Headaches disorientation and confusion and memory loss deficits in attention or concentration fatigue and irritability as well as emotional and behavioral changes. Often sleep difficulties and emotionally symptoms such as depression, anxiety, irritability or apathy also affect recovery.
Concussion
Trauma induced changes in brain functioning, subtle changes due to damage of neurons. typically caused by a blow to the head. Most common form of Trumatic brain injury. Injury affects functioning of the neurons and causes this orientation or loss of consciousness. Headache dizziness nausea impair coordination and sensitivity to light. Can last a few weeks and sometimes much longer. Amnesia free events prior to a concussion appears to be a strong predictor of the severity of the impairment following a concussion. 4 million per year due to competitive sports and recreational activities. Have to go unreported.
Cerebral contusion
Bruising of the brain often resulting from the blow that causes the brain to forcefully strike the skull. Unlike disruption in cellular functioning seen in the concussion, contusions involve actual tissue damage in the areas bruised. Similar symptoms to concussion. Often brings reoccurs both of the side impact on the opposite side of the skull.
Cerebral laceration
Open heaven Sharee and which brain tissue was torn pierced or rupture. Usually from the school fracture or an object that has penetrated the scope. As with a contusion damage is localized and immediate medical care focuses on reduce bleeding and preventing swelling.
Chronic traumatic encephalopathy CTE
Progressive degenerative condition diagnosed when Autopsy the reveals diffuse fuse brain damage resulting from ongoing head trauma. A person who have multiple episodes of head injury such as athletes or the military. It’s associated with psychological symptoms such as depression poor impulse control and increased risk of dementia it’s in four stages. Progresses slowly over decades eventually resulting in dementia
Stage one of CTE
Headache and loss of attention and concentration
Stage 2CTE
Depression, explosive outburst, and short term memory loss
Stage III CTE
Cognitive impairment, including difficulty with planning and impulse control
Stage four of CTE
Dementia, word finding difficulty, and aggression
Vascular neurocognitive disorder’s
Condition involving decline in cognitive skills due to reduced blood flow to the brain. Can result from a one time cardiovascular event such as the stroke or from unnoticed I’m going to scription’s blood flow within the brain. Symptoms involve complex attention, information processing, planning and problem-solving. Changes and motivation personality or Mood also common often begin with atherosclerosis. And plaque thickens in Narrows artery walls reduce blood flow to her brain and other organs.
Cardiovascular event
Pertaining to the heart and blood vessels such a stroke
Atherosclerosis
Clocking of the arteries resulting from a buildup of plaque
Plaque
Sticky material composed the fat cholesterol and other substances that builds up on the walls the veins or arteries
Stroke
Sudden halt in the blood flow to a portion of the brain, leading to brain damage. Fourth leading causes of death in the United States. Particularly high for African-Americans. Cigarette smoking contributes to one in for strokes. 50% in younger people. Women who Smoke you have a 60-80higher risk of stroke, especially hemorrhagic strokes particularly high for women Who smoke. Depression associated with 34% increase in risk for stroke. Major cause of disability
Hemorrhagic stroke
Stroke involving leakage of blood into the brain
Ischemic stroke
Stroke due to reserve first blood flow supply caused by a clot or severe narrowing of the arteries supplying blood to the brain. 87% of strokes
